So MANY smart people. The code will be cracked, and the world will enjoy a new renaissance of growth and clean energy. As the naysayers fade into the background, more will understand the potential and the efforts on MANY fronts will accelerate. Congratulations to the TSLA team for helping lead the way.
You'll still have a bunch of peasants and poor people burning wood or what ever else for fuel. Vehicles driven by gasoline, diesel will still exist because again poor people can't afford clean energy. There are many poor countries out there don't kid yourself into thinking they will change any time soon.
